BACKGROUND OF INVENTION 1. Field of the Invention

The present invention relates generally to a technical field ofventilation device, and more particularly to a ventilation device whichis mounted on a ceiling or a wall of a bathroom and capable ofventilating the bathroom.

2. Description of Related Art

The ventilation device has been widely used in the bathroom of thefamily because of its function of adjusting the air and changing the airflow. Conventional ventilation devices comprise a housing defining aninternal passageway, a fan rotationally disposed within the internalpassageway, and a motor disposed in the internal passageway to drive thefan to rotate. The housing has an air inlet and an air outletcommunicating with the internal passageway and the outside. When airenters the internal passageway from the air inlet, the fan located inthe internal passageway guides the air out of the environment from theair outlet.

However, after the conventional ventilation device is used for a periodof time, the exhaust efficiency of the fan located in the housing may bereduced due to dust accumulation. This may even cause damage to themotor that drives the fan to rotate. When replacing the motor, it isnecessary to hold the housing with one hand and remove the screws thatlock the housing and the fan and then the motor can be taken out fromthe internal passageway. In this way, not only is the process of takingout the motor quite inconvenient, but also, after replacing the motor,the screws need to be aligned with the screw holes for re-locking,making the replacement process more difficult. Therefore, the structuraldesign of the conventional ventilation device still needs to beimproved.

In view of this, how to improve the above problems and develop a moresimple and convenient way of disassembling and assembling theventilation device has become the subject of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1 and FIG. 2, the figures show a ventilation deviceused in a bathroom. The ventilation device comprises a housing (1)having an receiving space (11) disposed therein, an air inlet (12) andan air outlet (13) disposed at both sides of the receiving space (11)and communicating with the receiving space (11), a baffle piece (131)pivotally disposed at the air outlet (13), and a bottom cover (14)disposed at a bottom of the housing; a fan module (3) detachablydisposed in the receiving space (11) of the housing (1) and fastened tothe positioning member (2); and a power control device (4) disposed inthe receiving space (11) with its shell connected to the inner wallcorresponding to the housing (1) in a detachable manner. The powercontrol device (4) is electrically connected with the fan module (3),and has a wire-arranging element (41) for fixing the electric wires ofthe fan module (3).

With the design of fastening the fan module (3) to the positioningmember (2) in a detachable manner, a user can push the fan module (3) toslide the fan module (3) from the side edge of the positioning member(2) and remove out of the housing (1) to allow repair and maintenancemore simple and convenient.

The above two figures also show that the power control device (4) can beconnected to the inner wall corresponding to the housing (1) by usingmagnet (5) in a magnetic attraction manner. Of course, in addition tousing magnet (5) in a magnetic attraction manner, hooking (not shown inthe figure) or adhering (not shown in the figure) may also be used forconnecting to the inner wall corresponding to the housing (1). As aresult, the installed power control device (4) can be more firmly fixedand will not be fell off in removing the bottom cover (14) of thehousing (1) during maintenance. In addition, through the methods ofmagnetic attraction, hooking (not shown in the figure) or adhering (notshown in the figure), there is no need to use screws for connectionbetween the power control device (4) and the housing (1), which not onlysimplifies the structure, but also makes the installation easier.

As shown in FIG. 2, the wire-arranging element (41) is disposed at oneside edge of the power control device (4), and is a non-closed loop hookfor fixing the electric wires of the fan module inside. The top of onefixing pieces (311) is inwardly recessed with a receiving groove (313)for receiving the electric wire of the fan module (3). Therefore,through the collaboration of wire-arranging element (41) and receivinggroove (313), the electric wires between the fan module (3) and thepower control device (4) can be fixed to achieve good wire-arrangingeffect and solve the problem of electric wire storage.

As shown in FIG. 2a to FIG. 4, one end of the fan module (3) further hasa motor (31) fastened and fixed 10 positioning member (2). A pluralityof fixing pieces (311) is disposed around the outer edge of the motor(31). One end of each fixing member (311) has a snap slot (312) which isdisposed corresponding to the positioning member (2) and can be fastenedto the positioning member (2). Accordingly, when the motor (31) isdisassembled, the motor (31) only needs to be pushed to slide the snapslot (312) out of the side edge of the positioning member (2).Conversely, when the motor (31) is installed, the snap slot (312) onlyneeds to be embedded in the positioning member (2) in a slide way toimprove the convenience and save the time of assembly and disassembly.

The above only describes some exemplary embodiments of the presentinvention. Those having ordinary skills in the art may also make manymodifications and improvements without departing from the conception ofthe invention, which shall all fall within the protection scope of theinvention.
